Hi experts,

can any one give me a help

many thanks

Where I have to call the function above in  a module pool program, in module PBO or in PAI. I put it in init of PBO

F4IF_INT_TABLE_VALUE_REQUEST

[Former Member]

HI

You need to cal FM in POV (PROCESS ON VALUE REQUEST).

you need to seperate event for F4.

This message was moderated.

[former_member188103]

Hi Elina,

     It needs to be written in the PAI include.

Thanks & regards,

Bharat

[former_member397321]

So where I have to implement the form which calls the function. I'm askink it becouse The PBO; PAI has especific Include in the program.

So POV appears before PBO, is that?

[Former Member]

Hi,

Before calling FM F4IF_INT_TABLE_VALUE_REQUEST  you need to call 'DYNP_VALUES_READ' FM to get input fields.

Thanks,

Sree

[Former Member]

Hi

write down pov after PAI event.

POV routines comes in PAI include.

i think no need of DYNP_VALUES_READ Fm in module pool that requires in REPORT program @ Polu Sreedevi

laxman

You can check out this thread as well if you are still not clear.

These as well

[former_member397321]

Hi experts many thanks I have made a progress,

The error doesn't appear.... so  when I called the function, in the Tables section I have the return table as you can see, it_return_tab, doesn't have values, and the  Search Help doesn't show value

	field_tab	= it_field_tab
	return_tab	= it_return_tab

[former_member397321]

HI EXPERTS,

WHAT CAN I DO FOR THE VALUES OF MY SEARCH HELP ITAB APPEARS IN THE SCREEN.

I LOOK FORWARD TO HEARING FROM YOU.

[Former Member]

once try press enter fist and press f4.

[Former Member]

TRY THIS,

CODE ON SCREEN.

PROCESS ON VALUE-REQUEST.

   FIELD it_zcc02_bankl MODULE SHOW_SHP.

   CODE IN MODULE SHOW_SHP

    ****  FIRST GET DATA********

    free field_tbl.

   field_tbl-tabname    = "TABLE NAME.

   field_tbl-fieldname  = "FIELD NAME.

   field_tbl-selectflag = 'X'.

   append field_tbl.

   call function 'HELP_VALUES_GET_WITH_TABLE'              

     exporting

       show_all_values_at_first_time = 'X'

     importing

       select_value                  = select_value

     tables

       fields                        = field_tbl

       valuetab                      = ITAB

     exceptions

       others                        = 99.

   if sy-subrc eq 0.

     it_zcc02_bankl = select_value.

   endif.

[former_member397321]

OTHER INFORMATION IS THAT, THE ITAB I GAVE AS A PARAMETER TO THE FUNCTION HA VALUE, IT IS 1280 RECORDS, AND THIS TOTAL OF VALUES IS SHOWN IN THE SEARCH HELP BUT VALUE DOESN'T APPEAR.

KIND REGARDS

[former_member397321]

I have presssed F4 boton and enter the value isn't shown

[former_member397321]

have a look of what I'm saying:

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

    EXPORTING

      display         = rfcu3-xshow

      retfield        = 'bankl'

*      dynpprog        = 'ZTRDCCHQ'

*      dynpnr          = '0201'

*      dynprofield     = 'it_zcc02-bankl'(014)

      value_org = 'S'

    TABLES

      value_tab       = txttab1

      field_tab       = it_field_tab

      return_tab      = it_return_tab

    EXCEPTIONS

      parameter_error = 1

      no_values_found = 2

      OTHERS          = 3.

  IF sy-subrc <> 0.

    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

  ENDIF.

  LOOP AT it_return_tab INTO wa_return_tab.

    p_it_zcc02_bankl = wa_return_tab-fieldval.

    EXIT.

  ENDLOOP.

my field is p_it_zcc02_bankl, my

value_tab

= txttab1

has a value before I call the function

[Former Member]

you shoudl press enter before F4,

and check in the debugging whether that internal table having any data or not.

[former_member397321]

Hi, are you there?

kind regards

[former_member397321]

Hi experts,

I have pressed and the internal table I'm passing in the function has a value- 1280 records but it isn't shown in the screen

why?

kind regards

[Former Member]

you shoudl press enter before F4,

and check in the debugging whether that internal table which you are passing to function having any data or not.

[former_member397321]

Expert Laxman,

as I have wrote, the internal table has values about 1280 records, and I can see it in the debug, but values doesn't appear in the screen,

why

[former_member397321]

Hi experts,

That is the step where I am.

I have debugged the program and the itab I have passed by the parameter value_tab of the function has values- about 1280 records.

When I press F4, itab or tab appears in the screen but I can't see the in the bottom of the tab there are information which says 1280 records was selected,

My doubt is, why the I can't see the values of the itab or tab of F4 in the screen?

I will be thankful if anyone could help

[former_member397321]

Is it the code below corect:

fldtab1-tabname

= 'itab1'.

  fldtab1-fieldname  = 'CHAVE'.

  fldtab1-selectflag = 'X'.

  APPEND fldtab1.

I have filled fldtab1-tabname with itab and not transparent table name

kind regards

[former_member397321]

Tell me who could help,

Does the field on the screen need to be any field of a transparent table or it should be an internal table field.

kind regard

[former_member397321]

Hi experts,

I get the solution by changing values of tabname and fieldname, giving values of transparent table in both.

fldtab1-tabname

= 'bnka'.

  fldtab1-fieldname  = 'bnkl'.

  fldtab1-selectflag = 'X'.

  APPEND fldtab1

I was giving values of the internal table.
